UNITED STATES PATENT OFFICE,

WILLIAM JOHN FREDERICK YOHNKA, OF EXLINE, ILLINOIS.

FODDER=STACKER.

SPECIFICATION forming part of Letters Patent No. 363,877, dated May 31,1887.

Application filed September 18, 1886. Serial No. 213,958. (No model.) I

To aZZ whom it -may concern.-

Be it known that I, WILLIAM J OHN FRED- ERICK YOHNKA,a citizen of theUnited States, residing at Exline, in the'county of Kankakee and Stateof Illinois, have invented certain new and useful Improvements inFodder- Staokers; and I do declare the following to be a full, clear,and exact. description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accoin-- panying drawings, and to the lettersand figures of reference marked thereon,which form a part of thisspecification.

The invention will first be described in connection with the drawings,and then clearly pointed out in the claim.

Figure 1 of the drawings is a front view of the stacker, and Fig. 2 avertical section of the same on line as m, Fig. 1. I

In the drawings, A represents a frame nearly or quite in theform of aright-angled triangle, the hypotenuse consisting of the two parallelinclined bars a a, on which slides the foddercarrier B, whose twoparallel bars,b b,fit snugly between the bars a a, so that the trough orfodder-holder I) cannot suffer lateral displace ment. On each of thebars b are hooks b correspondingly placed, so that as the carrier Breaches the top of frame A they will catch upon the rod 0 and turnit'over, so as to throw the fodder upon the stack.

D is a platform pivoted across its middle to the rod 0, sufficient spacebeing left between it and the frame-bars a afor the passage of the barsb b. The lower end of the platform D is held down by lever-hooks F F,fulcrumed on a cross-bar, E, secured to the bars a a a little belowtheir upper ends. Said platform conforms to the inclination of the barsa a, so that. the carrier may pass over it. The lever-hooks F arefulcrumed to the bar Eand weighted at the rear end, so as to hold themover the bar d, which forms the lower end of the platform;

When the carrier is passing up the platform D it pushes against andunhooks the levers F and engages the rod 0, so that the carrierB andplatform D may turn and throwthe fodthe bottom of the platform, slidesup through the eye e on cross-bar E, and finally catches in the saideye, so as to prevent the platform from turning too far. As soon as thedraftrope is slackened the carrier will begin to turn back with theplatform and will be carried down by its own weight.

The elevator-frame A is provided with a pivoted bar, G, near-the bottom.On the end of this bar-is a loop, 9, through which a stake may be drivento retain the frame in a fixed position. A second pivoted bar, G, may beplaced'upon the sired.

. To the carrier B is attached a rope, H,which passes over a pulley, I,in the platform D and then down under a pulley, J, near the bottom offrame A to the singletree at which thehorse works. As soon as thecarrier B on the platform D has unhooked the levers F and engaged therod 0 with its hooks b the pull on the rope dumps the fodder on thestack.

Having thus described all that is necessary to a full understanding ofmy invention, what.

I claim as new, and desire to protect by Letters Patent, isa Thecombination, with the frame A, having a cross-rod, O, at the top and a'carrier, B, which slides up and down on an incline of said frame, of theplatform D, pivoted at or near its middle on the'rod O, and the endweighted hook-levers F F, fulcrumed on bar E, whereby said carrier mayfirst slide up on the platform D, next push against and unfasten thelevers F, and finally turn over with theplatform by catching said rod 0with hooks on the under side of said carrier,substantially as shown anddescribed.

In testimony'whereof I have aflixed my signature in presence of twoWitnesses.

WILLIAM, JOHN FREDERICK YOHNKA.
